Forced vibration analysis of plate is growing research subject as plates are used for manufacturing many mechanical structures. The analytical solutions have been found for plates with specified mass and stiffness but for the plates with uncertain mass and stiffness are studied very limitedly. The uncertain parameters play an important role in the design of practical mechanical system. It becom...

BACKGROUND Parkinson's disease is caused by a dopamine deficiency state in the fore brain area. Dopamine receptor agonists, MAO-B inhibitors, and N-Methyl-D-Aspartate (NMDA) receptor antagonists are known to have antiparkinson effect. Levodopa, a dopamine structural analog, is the best currently available medication for the treatment of Parkinsons disease. Unfortunately, it also induces side ef...

abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...

Purpose: The patellofemoral pain syndrome (PFPS) is one of the most common musculoskeletal disorders of the knee joint. Hip muscles’ weakness is one of the reasons for PFPS occurrence. The aim of this study was to recognize the effective muscle group in prevention and treatment of patients with PFPS. Methods: This is a prospective and quasi-experimental study in which 30 participants (15 ...

The effects of neuromuscular blocking concentrations of hexamethomum and decamethonium on end-plate current parameters have been studied in frog sartorius nervemuscle preparations. In the presence of either drug, hyperpolarization of the cell membrane reduces the peak amplitude of the end-plate current despite the increase in driving force. The effect is larger for hexamethonium than for decame...

This paper investigates the effects of varying some of the explosion bulge test conditions on assessment of the plate deformation resistance (bulge depth and plate thinning), focusing on four parameters: (a) use of cardboard wrapping to provide thermal insulation for the test plate prior to blasting (b) changing the means of supporting the charge above the plate from a cardboard box enclosure t...

this article studied static deflection, natural frequency and nonlinear vibration of a clamped-clamped microbeam under discontinues electrostatic actuation. the electrostatic actuation was induced by applying ac-dc voltage between the microbeam and electrode plate. in contrast to previous works, it was assumed that length of the electrode plate was smaller than that of the microbeam. in additio...
